COM progress report

Hi,

I've noticed that other GSoC-ers are posting their updates to the list, 
so if nobody opposes I will do the same. My previous reports are 
available on my blog. I will be grateful for any suggestions regarding 
the director stuff mentioned in the second half of the report.

Thanks,
Jan Jezabek

This week I have been working mostly on smaller enhancements to the COM, 
with no major new features. These enhancements are:
- ability to specify CLSIDs and IIDs by the user on a per-class basis, 
as shown by the following example:

%feature ("iid", "11111111-1111-1111-1111-111111111111") A;
%feature ("clsid", "22222222-2222-2222-2222-222222222222") A;
class A { ... };

GUIDs can also be specified for the module class and also for the type 
library,
- I have implemented a GUID generation algorithm (as specified in RFC 
4122, variant 5). It uses SHA-1 hashing for generating the GUIDs. The 
user can (and should) specify one global GUID which can be thought of as 
a random seed (it is called 'name space ID' in RFC 4122); this GUID in 
binary form is prepended to the class name and afterwards the hash of 
this string is used as a source of bits for the CLSID and IID. This 
should practically guarantee uniqueness and determinism, and also save 
the user some work,
